here is an announcement of an AGN flare.  The redshift of 3C454.3 is 0.86.

> 3C 454.3 is in an high state, the REM observations obtained fews 
> minutes ago  show the source  at a  level of R=13.1 with a rising 
> trend during the last days. A very high state. This is also 
> confirmed by the Tuorla observations available on the WEB 
> (http://users.utu.fi/kani/1m/3C_454.3_l.png) . During the big May 
> 2005 outburst the source was R=12. but his minimum is around 16-17 mag.
>
> Please observe it all wavelengths if you can and inform the group 
> about our observations, we could test our capability to manage MW 
> campaign during this ourburst.

> I'll try to activate the WEBT too on this source..
